It’s my pleasure to announce the first milestone of Spring Data R2DBC. Spring Data R2DBC is Spring's client project for R2DBC. With Spring Data R2DBC you get end to end reactive ad-hoc query execution and Spring Data repositories for relational databases.

Spring Data R2DBC embraces functional-reactive integration of relational databases by providing DatabaseClient as its central abstraction. The following example shows how to bootstrap DatabaseClient without spinning up a Spring context:

PostgresqlConnectionFactory connFactory = new PostgresqlConnectionFactory…

Hi Spring fans! In this installment of Spring Tips we look at how to use Spring to work with infrastructure on the Google Cloud Platform (GCP)

speaker: Josh Long

Performance has always been one of the top priorities of the Spring Engineering team, and we are continually monitoring and responding to changes and to feedback. Some fairly intense and precise work has been done recently (in the last 2-3 years) and this article is here to help you to find the results of that work and to learn how to measure and improve performance in your own applications. The headline is that Spring Boot 2.1 and Spring 5.1 have some quite nice optimizations for startup time and heap usage. Here’s a graph made by measuring startup time for heap constrained apps:

On behalf of the community, I am pleased to announce that the Release Candidate 1 (RC1) of the Spring Cloud Greenwich Release Train is available today. The release can be found in Spring Milestone repository. You can check out the Greenwich release notes for more information.

End of Life (EOL) Reminder

The Dalston release train will reach EOL status at the end of 2018.

Notable Changes in the Greenwich Release Train

This milestone is compatible with Spring Boot 2.1.1.RELEASE. Updates were made across the projects for Java 11 compatibility.

Go to the Greenwich.RC1 github project to see all…

On behalf of the Spring Data team, I’m pleased to announce the availability of the first milestone of the Moore release train.

Notable changes include:

• Support for Streamable wrappers as query method return types.
• Additional Kotlin extensions like CrudRepository.findByIdOrNull(…).
• A Kotlin query DSL for MongoDB (special thanks to Tjeu Kayim)
• Gemfire & Apache Geode upgrades.
• Spatial type support for Neo4j.
• Elasticsearch REST and (initial) reactive client support.
• Support for Redis Streams.
• ...and tons of new stuff for Spring Data JDBC.

Please find a high-level overview of what has been added in our release wiki…

Hi Spring fans and welcome to another installment of This Week in Spring! This week I've been in Seattle, WA and now I'm off to Toronto, Canada for the epic SpringOne Tour Toronto edition, the last SpringOne Tour for the year, too! (Can you believe we're now less than 22 days from 2019? Time sure flies when you're having fun!)

• Spring Tips is back! And what a season have we planned for you! Last week we introduced the first new video, this one looking at the Spring support for Microsoft Azure. As always, you can see the whole playlist at the Spring Tips YouTube Playlist and you should check back on this very blog every Wednesday for the next few months for new installments.

Imperative code eats threads at the pace of incoming requests while Software is eating the world. This post discusses the assumptions for reactive programming on the JVM and what this means for integrations – in particular, relational databases.

The motivation to come up with a post is the constant increase in reactive programming adoption while some major building blocks are not yet available – in particular, the question: What about relational databases?

What is Reactive Programming

There are a lot of answers about what Reactive Programming is and how this compares to Reactive Systems. I see Reactive Programming as a programming model that facilitates scalability and stability by creating event-driven non-blocking functional pipelines that react to availability and processability of resources. Deferred execution, concurrency and asynchronicity…
